Hi I have been installing karma on my machine but am getting error while installing it.

ws@0.4.31 install /usr/local/lib/node_modules/karma/node_modules/socket.io/node_modules/socket.io-client/node_modules/ws
(node-gyp rebuild 2> builderror.log) || (exit 0)

@sunnymakani can you make sure you have the latest NPM?

It sounds like the common error when installing ws native module, which is however optional, NPM should ignore this. I don't think we can do anything about this in Karma.

[sunnymakani]

Turns out it was some problem with global installation of karma even though i issued npm install -g karma. This error is thrown but when we go to karma bin and then run karma commands it was running fine. Just appended the bin of karma to PATH variable and its working fine now.

@sunnymakani you should use karma-cli instead:

$ npm install -g karma-cli

then you don't need to care about PATH variables. 😄

[sunnymakani]

Thanks @cironunes will do going forward.. :)
